Epecification and Qualification of a Disimil Welding Procedure (wps) with gmaw Process, for Low Carbon and Martensitic Steel Sheets
Abstract
This work presents the design of a welded joint to establish the weldability conditions of two materials used in the automotive industry. The low carbon and martensitic steel have thicknesses of 1 and 1.1 mm respectively. The design of the welded joint was carried out considering each of the variables involved in the GMAW process that could affect them. After this process it was found that the sheets of the base material behave much better when the metal transfer system is by short circuit since the heat of contribution is lower. With this design it is possible concluding the WPS that was applied and subsequently qualified complies with all the parameters that allow to obtain a welded joint with the requested design characteristics.
