Welding
Welding – 12 Types Explained. Welding is a fabrication process that joins two or more metals using heat, pressure, or both to form a strong, permanent bond. Weldable materials generally include metals and thermoplastics, but welding other materials like wood are also possible. Modern welding was pioneered in 1800 when Sir Humphry …
Submerged Arc Welding (SAW): Working Process, Equipment, Parts, and Its Applications
Ramakant Sharma June 7 2020. Submerged arc welding (SAW) is a welding process where the tubular electrode is fed continuously to join two metals by generating heat between electrode and metal. The area of the arc and molten zone gets its protection from the atmospheric contamination by submerging under a blanket of granular flux.
Projection Welding
From a resistance welding point of view the part must be held or positioned in the proper orientation and alignment to meet the part specification. It must stay that way until the electrodes have closed on the part. Fixtures or tooling frequently perform this function. PIN LOCATING 4 PROJECTIONS.
