When it comes to brazing, there are two main equipment choices: setups utilizing oxygen/acetylene or those using air/acetylene torches Traditionally, oxygen/acetylene rigs have dominated many HVAC brazing applications across the United States. However, air/acetylene torches represent a viable alternative option. Contractors who have experimented with air/acetylene often value their enhanced portability and reduced operating …
Q: What shielding gas is most appropriate for arc welding aluminum? I’ve received differing recommendations – some say to use pure argon while others suggest helium is better. I plan to use both gas metal arc welding (GMAW) and gas tungsten arc welding (GTAW) processes. Can I use the same shielding gas for each …
The gas metal arc welding (GMAW) process, also known as MIG welding, is susceptible to various types of weld discontinuities or defects. This article outlines some of the frequently encountered issues. Excess Reinforcement Buildup When welding a joint from one side, the root side can experience a buildup of excess reinforcement or weld metal. …
