The safe ways to accomplish different types of welds

Welding Processes What is Welding? Welding is nothing more than the art of joining metals together.

Weld Types and Positions Overview Any discussion on weld types and positions starts with the idea that it is important to distinguish between the joint and the weld. Each must be described to completely describe the weld joint. There are many different types of welds, which are best described by their shape when shown in cross section.

Hi, my name is Garrett… owner of weldguru. The most popular weld is the fillet weld, named after its cross-sectional shape. Other types of welds include flange welds, plug welds, slot welds, seam welds, surfacing welds, and backing welds.

Joints are combined with welds to make weld joints. There are several types of fillet weld: A full fillet weld is a weld where the size of the weld is the same as the thickness of the thinner object joined together.

A staggered intermittent fillet weld refers to two lines of intermittent welding on a joint. An example is a tee joint see below where the fillet increments that are in one line are staggered in comparison to the other line.

Chain Intermittent Fillet Weld: Refers to two lines of intermittent fillet welds in a lap joint or T where the welds in one line are approximately opposite those in the other line. Other terms associated with fillet welds include: Boxing which refers to the continuation of a fillet weld around a corner of a member.

It is an extension of the principal weld. Refers to the maximum perpendicular distance from the face of a convex fillet weld to a line joining the toes. See figure below for fillet weld positions.

There are seven basic types of groove welds, which are shown in figure The groove weld refers to beads that are deposited in a groove between two members to be joined. Illustrations of Basic Groove Welds More examples are shown in figure The type of weld used will determine the manner in which the seam, joint, or surface is prepared.TIG Welding is also a slang term commonly used for Gas Tungsten Arc Welding or “GTAW".

TIG welding also goes by the term HeliArc welding. TIG welding is the most difficult of the processes to learn, and is the most versatile when it . SMAW, GMAW, and TIG Welding Comparison.

Types Of Welding Processes

SMAW, GMAW, and TIG are the most common welding methods in use today. TIG takes the most skill, since you have to hold a filler rod in one hand and the gun in the other in order to accomplish this type of welding.

It is usually reserved for specialized types of welds. Tulsa Welding School. The energy for gas welding comes from the combustion of a fuel with oxygen or air. A few of the most popular fuels are acetylene, Mapp gas and hydrogen.

Different Types of Welding

Since gas welding is slower and easier to control than electric arc welding, it is often used in applications . Joint Types The American Welding Society defines a joint as “the manner in which materials fit together.”As shown in Figure , there are five basic types of weld joints: • Butt joint.

• T-joint. • Lap joint. • Corner joint. • Edge joint. Joint Preparation Weld joints may be initially prepared in a number of ways. These include: • Shearing. Any conversation around welding starts with a discussion on welding position of the weld face. A number is used to define the position and an F for Fillet or G for groove refers to the type of weld.

An architect's blueprints would indicate the welding symbol. Different types of welding require the welder to use shielding gases that help keep the metal being welded free of contaminants, allowing for a solid weld to be produced.

Welds that are properly performed using shielding gases often have a cleaner look to them than those welded without the protection of a shielding gas.
