Welding is a necessary part of our work. Both pipefitters and welders must create strong connections between metals and understand how metals fit together. Local 537 is proud to provide first-class welding training so that our apprentices can get in the field and perform their job with excellence. The craft of pipe welding is and will likely always be in demand, due to the numerous ways we use it to build strong communities. Pipe welding is needed for oil and gas pipeline, scaffolding, structural applications such as fencing and handrails, and water and sewage piping.
