STS 436 및 내후성 강에 대한 GMAW 용접에서 경도 변화에 따른 재료의 고온균열 성질변화 고찰

A Study on Characteristics Variation of STS 436 and Weathering Proof Steel by Control of GMAW Speed - A Study on Changes in Welding Parts by Using EN 12072 G 18-8 Mn Welding Wire(2) -

In industrial sites trains or vehicles have been used to transport products as a general transportation way. For saving transportation cost it can be the key to produce a storing facility that is lighter, more long-lasting, stronger, and safer as the condition of the same weight. A container doesn t ask high technology to make but allows to carry lots of loads safely. Therefore It s important to achieve automated mass production system. In this study, its purpose is to manufacture a container that is durable and strong against corruption. Thanks to the welding wire diluted on the welding parts, ferritic stainless steel, and components of the weathering steel. To achieve the goal, GMAW welding varied on welding speed, welding wire, and protective gas is applied under the condition that ferritic stainless steel and weathering steel are folded so as to make a durable container compared to a common container. Supposing to know the changes of welded materials through the analyze of components variation after the completion of welding of using EN 12072 G 18-8 Mn welding wire, it s possible to create a better product by applying proper welding condition that can decrease welding defects.
