How to Weld a Socket Weld Fitting


One method to connect pipes together is to use a socket weld. The socket weld is inserted inside a pipe valve and welded on the outside. Socket weld fittings are used by plumbers, auto mechanics and home builders. The socket welds are created to prevent leaks, sustain a high level of pressure and made to be interchangeable. Welding a socket weld fitting can be achieved quickly using the right tools and resources.

Things You'll Need

  • Soap
  • Water
  • Dry cloth
  • Welding torch
  • Welding mask
  • Welding gloves
  • MIG Welding wire
  • Obtain the socket weld fitting. Select weld fitting that is made in the same material as the pipe. Choose between steel, aluminum or plastic.

  • Wash the pipe and socket weld with warm soapy water. Dry the area with the cloth.

  • Put on the protective gear. Welding gear includes the protective gloves and welders mask.

  • Light the welding gun. Open the acetylene gas regulator and press the striker to ignite the gun. Increase the flame by increasing the gas regulator level.

  • Attach the socket weld into the valve. Screw clockwise to tighten.

  • Weld the joint areas of the socket weld and pipe fitting. Melt the welding wire around the pipe edges by feeding the wire through the welding gun. Turn the gas regulator off when completed.

Tips & Warnings

  • Wear long-sleeved clothes to prevent burns.
  • Work in an area free from petroleum and grease products.
  • Light the welding gun with the striker only.
  • Perform welding functions in a well-lit and well-ventilated area.
