The total market for welding-related products is expected to reach $37.2 billion by 2025, with a compound annual growth rate (CAGR) of 5.1% from 2021 to 2025. The growth in the safety and protective equipment segment is expected to be the highest, with a CAGR of 7.6% during the forecast period.

Welding is a fabrication process that joins material like metals and thermoplastics by applying some pressure and either with or without the presence of filler material. Advantages of welding as a joining method include considerable freedom in design, a joined piece that is as strong as the base metal, and general equipment is not costly. Disadvantages of welding include possible residual stresses and distortion of the workpieces, edge preparation of the workpiece, and potential metallurgical changes.
