For a TC-L1b groove weld detail, the identified welding processes include Shielded Metal Arc Welding (SMAW), Flux-Cored Arc Welding (FCAW), and Gas Metal Arc Welding (GMAW) with the exception of GMAW-S (short-circuit transfer). This selection is based on the characteristics and requirements of the TC-L1b groove weld, which allows for a variety of welding processes that can effectively produce strong and reliable welds in various structural applications.

SMAW is commonly used for its versatility and ability to be employed in a wide range of conditions, making it suitable for different base materials and positions. FCAW is favored for its high deposition rates and suitability in field conditions where portability may be necessary. GMAW is applicable to a broad range of materials and thicknesses and is known for providing excellent arc stability and control, which is essential for achieving the quality required in groove welds.

The exclusion of GMAW-S from this category acknowledges that specific transfer methods within GMAW may not always meet the performance criteria required for certain construction standards. Therefore, the combination of SMAW, FCAW, and the specified type of GMAW ensures that the welding processes allowed for TC-L1b
