With bigger pipe dimensions, welding can sometimes be more economical than hard soldering since heat is applied specifically to the area of the weld seam for a reliable connection. With hard soldering, the whole fitting has to be heated instead. This can be a lengthy and time-consuming process as heat is rapidly dissipated and consequently more gas will be consumed. Additionally, capillary solder fittings are not available for dimensions exceeding 108 mm outside diameter.
