buying welding wire In addition to having to consider the nature of work done. and know the details of the work Also consider the appropriate size between the electrode and the workpiece itself. so that it can be used conveniently and to protect Dangers from electric welding work. The use of electric welding wire of each size must be considered as appropriate as follows.

buying techniques Electric welding wire. Don’t miss it.
In addition to various factors in choosing to buy welding wire. That has been mentioned above There are still many techniques for choosing to buy welding electrodes for consideration.
1. Work piece strength
Before welding, you must know the mechanical properties of the metal of the workpiece first. If it is a low alloy steel, electrodes should be selected based on strength values. by as close to the work metal as possible If it is mild steel (Low carbon steel) should choose welding electrodes in the 6013 group, which are electrodes with mechanical properties closest to the work metal.
2. Type of power used
Should choose to use welding electrodes that are suitable for the welding current. Because some types of electrodes can be connected well with direct current only. Or some types will work well with alternating current only.
3. Welding position
Refer to the symbols given in Welding electrodes such as the AWS system will assign the 3rd digit to indicate the welding position that can be welded in which welding position.
4. Characteristics of the connection and adjacent seams
For example Seam without incision Choose electrodes with a soft arc. because it will cause less deep penetration. It is also suitable for work with thin materials. For thick materials, electrodes with a strong arc should be selected. Based on the 4th digit for the A.W.S. standard.
5. Job Requirements
The composition of welding electrodes should be considered to match the functional properties of that workpiece, such as impact work, welding work used at low temperatures. or high temperature and in addition to having to consider the mixture of welding electrodes Toughness and impact resistance must also be considered. which electrodes suitable for such usage conditions will be low hydrogen wire
This is all you need to know about. electrode Including techniques for choosing to buy welding electrodes for use at We have gathered together
