How Do I Learn To Weld?

Types of Welding

Arc Welding

Arc welding is one of the most commonly used welding techniques. It involves creating an electrical arc between the base metal and an electrode to fuse them.

The intense heat generated by the arc melts both the metal and the electrode, creating a molten weld pool, which solidifies to form a strong bond. Arc welding is versatile and can be used with various metals and alloys, making it suitable for various applications.

MIG Welding

MIG (Metal Inert Gas) welding, also known as Gas Metal Arc Welding (GMAW), is a popular welding method that uses a continuous feeding wire electrode and a shielding gas to protect the weld pool from atmospheric contamination.

MIG welding is known for its high productivity and ease of use, making it suitable for amateur and professional welders. It is commonly used in the automotive, construction, and manufacturing industries.

TIG Welding

TIG (Tungsten Inert Gas) welding, called Gas Tungsten Arc Welding (GTAW), is a precise welding process using a non-consumable tungsten electrode and a separate filler rod.

TIG welding produces high-quality, clean welds with excellent control over heat input and minimal spatter. It is commonly used in aerospace, automotive, and artistic applications where aesthetics and precision are essential.

Flux-Cored Arc Welding

Flux-cored arc Welding (FCAW) is similar to MIG welding but utilizes a hollow flux-cored electrode instead of a solid wire.

The flux inside the electrode provides a shielding gas and helps produce a slag that protects the weld pool from impurities and contamination. FCAW is preferred for outdoor applications or environments where wind or drafts can affect gas shielding.

Oxy-Fuel Welding

Oxy-fuel welding (OFW) is a welding process that combines fuel gas and oxygen to create a flame that melts the base metal. This molten metal is then united using filler rods.

Oxy-fuel welding is mainly used for maintenance, repair, and artistic applications. However, it has become less commonly used in industrial settings due to the emergence of more efficient and precise welding methods.

Safety Precautions

Protective Gear

When it comes to welding, safety should always be the top priority. Before starting any welding project, ensure you have the proper protective gear.

This includes a welding helmet with a dark-tinted lens to protect your eyes from the intense UV light emitted during welding. Welding gloves, made from heat-resistant materials, will shield your hands from high temperatures and sparks.

Welding gloves are designed to provide heat resistance and protect your hands from sparks, hot metal, and potential burns. They are typically made from a combination of leather, Kevlar, and other heat-resistant materials. Choose welding gloves that fit well and provide skill, allowing you to handle welding equipment and workpieces without compromising safety.

Welding Apron

A welding apron is a protective garment that covers your torso and legs, shielding them from sparks, UV light, and hot metal. It is usually made of flame-resistant leather or heavy-duty cotton fabric. A welding apron helps prevent burns and keeps your clothes from catching fire. Choosing an apron that provides adequate coverage and fits comfortably is essential.

Understanding Welding Techniques

Preparing the Metal

Before starting any welding project, preparing the metal surfaces that will be welded together correctly is crucial.

This typically involves cleaning the metal to remove any dirt, rust, or contaminants that can affect the quality of the weld. Depending on the metal and its condition, you may need specific cleaning methods such as wire brushing, grinding, or chemical cleaning. Proper preparation ensures good fusion, minimizing the risk of defects.

Setting Up the Welding Machine

Each type of welding process requires specific machine settings and parameters. Familiarize yourself with the controls and functions of your welding machine.

Set the appropriate voltage, current, and wire feed speed according to the material thickness, electrode or filler metal type, and desired weld quality. Always follow the manufacturer’s guidelines and consult welding charts or reference materials to determine the optimal settings for your specific welding task.

Striking an Arc

Striking an arc initiates the electrical arc between the electrode and the workpiece. Maintaining a safe distance between the electrode and the workpiece, usually around 1/8 inch, is essential to prevent the electrode from sticking to the metal. To strike an arc, briefly touch the electrode tip against the workpiece and quickly pull it back. This action creates the arc and initiates the welding process.

Controlling the Welding Pool

Once the arc is struck correctly, it is essential to control the size and shape of the welding pool. The welding pool refers to the molten metal created by the arc’s heat.

Proper pool control ensures the weld penetrates the base metal and strengthens the bond. By manipulating the angle, speed, and distance between the electrode and the workpiece, you can control the size and shape of the pool, ensuring a consistent and quality weld.

Fusing the Metal

The final step in welding is to fuse the metal pieces. This is achieved by feeding the electrode or filler metal into the welding pool, creating a molten bond with the base metal.

Maintaining a steady and consistent motion is essential, moving the electrode along the joint to ensure proper metal fusion. The speed and technique will vary depending on the welding process and the joint configuration.

Practicing Welding Joints

Butt Joint

A butt joint is formed by placing two pieces of metal together, edge to edge. It is one of the most common types of joints used in welding.

To weld a butt joint, the edges of the metal pieces are beveled or prepared appropriately and then welded along the entire joint length. Proper alignment, fit-up, and control of heat input are crucial in achieving a strong and structurally sound weld.


A T-joint, as the name suggests, is formed when one piece of metal is welded to the surface of another metal, creating a T-shaped configuration.

Welding a T-joint requires proper positioning, alignment, and heat control to ensure proper fusion along the joint’s horizontal and vertical axes. It is common in structural welding, where two members intersect at a 90-degree angle.

Lap Joint

A lap joint is formed by overlapping two metal pieces and welding them together at the point of overlap. It provides good strength and is commonly used when joining thin sheets or plates.

Proper preparation and fit-up are essential to ensure adequate penetration and fusion along the lap joint. Techniques such as stitch welding or plug welding may reinforce the joint further.

Corner Joint

A corner joint is formed when two metal pieces intersect at a 90-degree angle. It is commonly used to construct boxes, frames, or similar structures.

Welding a corner joint requires careful preparation, alignment, and control of heat input. Proper fusion and penetration at the corners are crucial to ensure a structurally sound weld.

Edge Joint

An edge joint is created when two metal pieces are aligned parallel to each other, with the weld running along the edge of the joint.

It is commonly used to join metal plates or sheets end-to-end. Careful preparation, fit-up, and heat control are essential to achieve a smooth and robust weld at the edge joint.

Weld Defects and Troubleshooting


Porosity is a common welding defect characterized by small cavities or voids within the weld. It is caused by trapped gases, such as hydrogen or nitrogen, being released during solidification of the molten metal. Porosity weakens the weld and reduces its integrity. To prevent porosity, ensure that the metal surfaces are clean, use the appropriate welding technique and settings, and avoid excessive moisture or contamination during welding.


Cracks in welded joints can occur due to various factors, including excessive heat, stress, or poor welding technique. Different types of cracks exist, such as longitudinal, transverse, and crater. To prevent cracks, ensure proper heat control, use appropriate preheating or post-weld heat treatment if required, and select the correct welding procedure and filler metal for the specific application.

Incomplete Fusion

Incomplete fusion occurs when the weld does not penetrate or fuse with the base metal properly. This defect weakens the joint and can lead to structural failure. Improper welding techniques, poor fit-up, or the wrong parameters for the specific welding process can cause incomplete fusion. Ensure proper joint preparation, maintain the correct angle, speed, and distance between the electrode and workpiece, and adjust the welding settings to achieve proper fusion.


Undercut is a groove or depression that forms along the edges of a weld joint. It occurs when the molten metal fails to fill the joint adequately and instead flows away, leaving a concave groove. Undercut weakens the joint and creates stress concentration points. To prevent undercut, ensure proper heat control, maintain the correct electrode angle, and consider adjusting the welding parameters or joint design if necessary.

Excessive Spatter

Spatter refers to the tiny, undesirable droplets of molten metal expelled during welding and can land on surrounding surfaces. Excessive spatter can increase cleanup time and affect the weld’s appearance and quality. To minimize spatter, ensure proper electrode angle, use the correct shielding gas and wire feed speed, and consider using anti-spatter compounds or sprays.

How Do I Learn To Weld?

Welding Positions

Flat Position

The flat position is the most common and easiest welding position. It involves welding on a horizontal surface, with the weld pool facing upwards. Gravity helps hold the molten metal in place, making it easier to control the weld pool and ensuring proper fusion. The flat position is commonly used for fillet welds, lap joints, and butt joints.

Horizontal Position

The horizontal position is when the welding is done along a vertical joint, with the weld pool flowing from top to bottom. Welding in the horizontal position can be more challenging due to the tendency of the molten metal to sag or move. Proper manipulation of the electrode angle and travel speed is necessary to ensure proper fusion and prevent the weld pool from getting too broad or concave.

Vertical Position

The vertical position involves welding on a vertical or nearly vertical surface, with the weld pool flowing downwards. Welding in the vertical position requires careful control of the weld pool to prevent it from sagging or falling. Proper technique, including shorter arc lengths and slower travel speeds, is essential to achieve good fusion and uniform reinforcement along the joint.

Overhead Position

The overhead position is the most challenging welding position due to the gravity pulling the molten metal downwards. Welding overhead requires high skill and control to prevent the weld pool from sagging or falling. Proper manipulation of the electrode angle, travel speed, and welding techniques, such as weaving or backstepping, are crucial to achieve adequate fusion and ensure a sound weld.

Understanding Welding Symbols
