Ironworking Navigation 


Welding is the process of joining metal components by heating them to their melting point and introducing a molten filler metal along their surfaces to create a joint. Welding is an essential component of steel fabrication and construction. Welding is an art. It takes time to learn, and sometimes years to master. Accomplished welders can judge the quality of their welding by sight and by sound and can often quickly troubleshoot common problems that stem from the setup of the welding machine to the condition of the welding lead and connections. The same visual cues that aid a welder in determining the strength and quality of his or her weld are often the same ones used by the certified welding inspector who must sign off on the safety of the welds that he or she puts down. The quality put into a welding application is a product of addressing the site conditions that negatively affect the welding process in order to establish and maintain an effective weld. Given the various welding processes and their varied applications the welder spends a lot of time practicing them in the various positions they will be applied. The accomplished welder has tested acquired the certification to run a weld process in the corresponding position prior to being called to out to do it for a specific welding job. The welder must have patience and a steady hand even when the process requires the welder to get into an uncomfortable stress position for long periods of time. Not all welding is inherently safe or easy. The Welding Ironworker can recognize the hazards and the obstacles to a welding application and can meet those challenges to create successful and safe welds.
