Full Answer

Fusion welding works well for connecting metal and plastic items. The manufacturing process uses several types of fusion welding to connect materials. Arc welding involves creating an arc of electricity to heat materials to their melting point. Oxy-fuel welding uses fuel gases combined with pure oxygen to increase the heat. Electric resistance welding, a type of fusion welding used for spots and seams, uses a combination of electrical distance and force over a period of time to melt materials together.
