Gas Metal Arc Welding (GMAW) is fast and economical. As shown in Figure 2, a continuous wire is fed into the welding gun. The wire melts and combines with the base metal to form the weld. The molten weld metal is protected from the atmosphere by a gas shield that is fed through a conduit to the tip of the welding gun.

Vertical welding is one of the four basic welding positions where the joint's axis is vertical to the ground, at an angle ranging from 45° to 90°. If you have a fillet weld in a tee or lap joint, it's called a 3F position. If it's a butt joint with a groove weld, it's a 3G position.
A good maintenance program, as well as rebuilds or upgrades when necessary, is essential. 6. Mill in misalignment. Tube mill misalignment, poor mill condition, and inaccurate setup account for 95 percent of all problems in tube production. Most mills should be aligned at least once a year. 7. Tooling in poor condition.
