SMA: Shield Metal Arc Welding (SMAW) SMAW is the most widely used welding process for metal fabrication because of its low cost, flexibility, portability, and versatility. The welding machine itself can be as simple as a 110-volt, step-down transformer that can be plugged into a normal electrical outlet. The electrodes are available from a large number of manufacturers in packages ranging from 1 lb (0.5 kg) to 50 lb (22 kg). The SMAW process is very versatile because the same SMA welding machine can be used to make a wide variety of weld joint designs in a wide variety of metal … Continue reading What are the advantages of SMA welding?
Purpose of Welding proximity requirement is: 1 – To avoid the overlapping HAZ, the lowering of the welding HAZ mechanical properties which is not covered in WPS is approved for welding configuration. 2- To avoid the duplicate of residual stress between two joints which may combine with the load during service, this leads to structural failure due to the total combined local stress exceeding allowable stress. Weld proximity is covered by a number of international standards. Extracts from these standards are shown below and summarized in the following table: Standard Applies to The minimum distance between weld toes Notes BS … Continue reading WELD PROXIMITY
