Copper Craft Production Welding Processes


Welding is one integral part of the production process of manufacturing copper craft. Other manufacturing processes that have been known among other processes putty (Hammered metal), formation (metal forming), machining (machining), and Finishing Color (Finishing color). Products with complex shapes and large size can be made by molding techniques. Products such as pipes, plates and sheets, steel-steel construction is made with the process of formation. Products with a strict and meticulous dimensions can be created by machining. What about the welding process? The welding process which in principle is to connect two or more components, more precisely directed to assemble (assembly) number into a form of machine components. Assembled components may be derived from the product of casting, forming or machining, both from the same metal or different.

Welding (Welding) is one of the Copper metal splicing techniques by partially melt the parent metal and filler metal with or without pressure and with or without additional metal and produces a continuous connection. From the definition there are four key words to clarify the definition of the welding is melt some of Copper, Copper fillers, pressure and continuous connection. From the definition above, the welding process scheme can be made as follows:

Another way of splicing has been known for a long time is in addition to splicing by welding brazing and soldering. The difference with welding brazing and soldering was not to melt the parent metal Copper metal just filler only. While the difference between brazing and soldering is located at the melting point metal filler. Melting point of the brazing filler metals ranging from 450C - 900C. As for the soldering, melting point metal filler is less than 450C.

From the chart above, it can be seen that the welding process can be divided into 3 main sections, namely melting welding (fusion welding), welding does not melt (solid state welding) and soldering / brazing. Thus, in carrying out the welding required to melt the metal and the tool or appliance for heating and emphasize both the metal (Copper-Brass) to be connected. Defrost and heating equipment or metal (Copper-Brass) can be based on the use of electrical energy, gas energy or mechanical energy.
