Butt Welds Explained: What Are They? When Are They Used?
Square Butt Weld. Square groove butt welds are the simplest joint design. It''s used with metal up to 3/16 in. thickness and when the weld joint won''t sustain constant load. The joint can have a root opening or have a tight fit between the workpieces. But depending on the metal and filler material, the root opening may be necessary.
Welding

For each joint configuration, either butt or fillet weld, consideration is given to the material grade and thickness and anticipated fit-up tolerances likely to be achieved in practice. Process ...
What is Welding?
Welding is a fabrication process whereby two or more parts are fused together by means of heat, pressure or both forming a join as the parts cool. Welding is usually used on metals and thermoplastics but can also be used on wood. The completed welded joint may be referred to as a weldment. Some materials require the use of specific processes ...

Butt Welds Explained | YesWelder
Butt joints are the easiest to weld since the gravity is working for you. Most butt welding joints are parallel and placed in a flat position, and you simply weld on top of them. As you weld, gravity pulls the molten weld puddle inside the welding joint, which allows you to fill the gap appropriately.
