Yes, there are some special considerations when welding Monel alloy 400 strips. It is important to preheat the material before welding to prevent cracking & warping. It should be welded using a filler metal that is also made from Monel alloy 400 or a similar nickel alloy. The surfaces of the Monel alloy 400 strips should be cleaned thoroughly before welding to remove any dirt, oil, or another contaminant that could affect the quality . Also, can be welded using various welding techniques such as gas tungsten arc welding, gas metal arc welding, shielded metal arc welding, & resistance welding. However, Monel alloy 400 is a relatively hard & brittle material, so it may be more difficult to weld than other metals. After welding, it should be stress relieved at a temperature of between 800°F to 1000°F (427°C to 538°C) for about 1 hour per inch of thickness. Welding should be done by a qualified welder, and the welding procedure should be in accordance with the manufacturer’s recommendations & industry standards.
