Abstract

High strength low alloy steels are types of alloy steels that provide better mechanical properties and greater resistance to corrosion than carbon steel. They are utilized in cars, trucks, cranes and bridges. For the welding of these types of steels, gas metal arc welding is possibly the most common method. Unfortunately, GMAW of these steels are associated considerable distortion, and the cost of the manufacturing process increases as a result of uncontrolled or unnecessary distortion. Gas metal arc welding of high strength low alloy steels implemented by using two technique: clamps and post-heating techniques. Results showed that the angular distortion was notably reduced through the use of the post-heating technique.
