An Overview
A job that revolves around the use of metal or that repairs metal requires a welding machine to be successful. The most flexible method for joining metal pieces is welding, and its effectiveness depends on the type of metals in operation.
Welding operations require you to consider factors such as the position, speed of travel, fill amount, and penetration. The fast filling material is appropriate for heavy welds that require a deposit of a large amount compared to a small weld. Thick metals require a deeper penetration than light metals that can burn through on this application. A poor weld quality can bring you many costly production issues.
Efficiency and quality determine the effectiveness of a welding machine in its operation. Ensure you test the quality of your weld method using destructive and non-destructive ways to check for things such as burns, cracks, defects, gas inclusion, and deficient wire delivery.
Tips For Selecting An Ideal Welding Machine In Australia
Nature of the metal
Welding takes place on carbon steel because of its properties that make it handle any excess heat applied on the metal and is compatible with most welding machines. MIG or TIG welder is compatible with stainless steel welding and requires less strength to operate than carbon steel. More complex welding machines such as the MIG machines are suitable for aluminum. It is recommendable to know the type of metal you will use before selecting a welding machine.
Ampere range
The current generation capacity determines the cost of a welding machine; therefore, ensure you pay attention to the thickness of the material you are using. You will need more current to weld thicker metal than in thin metals that require the proper amount of welding heat.
The welding location
A suitable welding machine depends on the area where the welding will take place. Indoor welding requires a welder that operates on 220 – 240 volts or 115volt AC. 115 volt AC is the supply for domestic location.
Compressed gas requirements
Several welding procedures use different compressed gases such as carbon dioxide, argon, and oxygen. Find out if your welding machine requires a compressed gas before purchasing.
Available local dealers
It is recommendable to purchase your welding machines from reputable retailers who receive their supply from legit manufacturers such as Kemppi Welder. You will get incredible discounts after purchasing from retailers who deal in these products in large quantities. It is easy to access other welding tools such as welding accessories, gas cutting accessories, and gas adapters in these shops. Alternatively, you can shop online after researching the best online suppliers that offer high-quality welding machines at an affordable fee.
Common Welding Processes
TIG welding
The method suits a wide range of metals such as titanium, copper, brass, magnesium alloys, and stainless steel. It uses a tungsten electrode and a compressed gas delivering a precise weld with aesthetic appearance and high quality. A person without experience can use this method because it does not require a much higher operator experience.
MIG welding
It is an easy process to learn with more operators available hence it is affordable. The metal is ideal for use in thin metals because it provides control. The pulsed MIG process is an extension of the stand MIG process. It is used in high-quality, thick metals such as superalloys, aluminum, stainless steel. Cleaner welds result from these two processes with less slag.
Flux core welding
The method is ideal for deep penetration on thicker sections of metal and commonly applies to thick metals and stainless steel and thus not suitable for other metals for future production.
