tig welder The Benefits of Using Welders in Industries
This saves time and money on electrode replacement down time while keeping stub waste to the bare minimum. The electrodes come in spools as small as 1 lb that are made for small production runs and cab be as large as 100lbs or more. This keeps production flowing without many interruptions for electrode replacement. MIG also allows welding of different metal thicknesses with a single diameter electrode. This is where production can be increased based on the machine settings. The electrode speeds are regulated in IPM or inches per minute and that means that production rates can increase based on machine settings.
MIG welding is a process that can weld almost any metal out there. The weld quality is excellent compared to most other types of processes with the ability to weld different metal thicknesses with a single diameter electrode. Some of the metals that it can weld are:
- Carbon Steel
- Stainless Steel
- Aluminum
- Nickel Alloys
- Copper
- Titanium
Another benefit of MIG welding is that the welds are clean and there is not much slag to clean (if any). The electrodes use a shielding gas to keep the atmosphere out of the weld area and that translates to saving time and labor costs on cleaning welds. Unlike Stick or Flux cored arc welding there is no flux on the electrode that requires the weld to be cleaned and dressed. The most cleaning that may be required can be done with a wire wheel.
In the end MIG welding is a great welding process for companies that need fast, clean, quality and low cost welds for their production needs.
What is the Short Circuit Transfer Type?
The short circuit transfer type happens when the MIG welding electrode starts short circuiting onto the weld joint. The way this type of transfer works is the MIG welder electrifies the filler wire and then the machine feeds that wire into the weld joint. Once the wire or electrode makes contact with the weld joint a short circuit is created. This short circuit heats up the wire until it melts and breaks off. After that the process keeps repeating until the welder stops welding. This transfer type simply shorts the electrode against the weld joint until it fills the weld joint.
When is Short Circuit Used?
Short circuit is used on thinner metals. The main reason behind this is that the voltage is on the lower end of the MIG welders settings. Short circuit is best used on metals 1/4 of an inch or less in thickness. If welding thicker metals the lower voltage will not allow the weld to penetrate properly. This will result in a weld that is either not strong enough or might produce a layer of weld that is literally not bonded to the joint. If the welder does not set the machine correctly on thicker metals the weld can be removed from the joint with nothing more than a tap of the hammer. This is the main reason why this type of transfer is used on thinner metals and requires less voltage.
How to Set-Up Your MIG Welder
Setting up your MIG welder requires two main ingredients and they are:
- Shielding gas with a high percentage of carbon dioxide
