Welding in San Antonio Welding is the fabrication of metals by melting together their surfaces. When two pieces are heated to a high temperature, they will be joined together after the texture melts and becomes tacky. This process is called welding. The melted metal forms its coating that prevents oxygen from reaching the molten metal, solidifying it into one piece. Welding an object like a car frame may require heating it with gas torches to very high temperatures before it can be molded successfully; this results in stronger joints than either metal possesses on its own. This is because the heat causes expansion of the metal, bringing alloying elements closer to each other so they can bond easier. https://alamo-city-custom-welding-construction.business.site/posts/5509700310019428563
