A big portion of plumbing is the act of cutting, bending, and connecting pipes. In order to create a watertight and reasonably permanent connection, plumbers stand by a number of traditional methods for joining pipes. One of these trusty methods includes 焊接.

早在5点,1000年前, there is evidence that 焊接 was being used to make jewelry items, 烹饪器皿, 做饭的工具, 组装彩色玻璃. 几个世纪以来, 焊接 has been seen as one of the simplest and most widely used methods for securing metal joints and seams, especially in creating connections between copper pipes in plumbing systems, 包括水, 浪费, 和排气管道.  

The 焊接 process works in joining two or more metals together by melting or putting a filler metal (solder) into the joint. The filler metal has a lower melting point than the adjoining metal. 焊接 differs from welding because it doesn’t involve melting the work pieces. Below are pros and cons surrounding this connection method:

All 焊接 calls for coating the metal with a flux before the solder is applied. Flux provides cleaning of the joint and can even act as a wetting agent in the 焊接 process. There are many different types of flux but plumbing applications typically use an acid-based (hydrochloric acid) flux.

Pipes, valves, and fittings make up the heart of plumbing. Traditional connection methods such as 焊接 allow these components to be joined and make for an efficient plumbing system. For more information on the act of 焊接 plumbing components together, take our ‘焊接AYU航向.
