A Dangerous and Challenging Job of MIG Welding Underwater

MIG welding underwater is not a common practice and is generally not recommended due to the high risk of electrocution. Welding produces a large number of sparks and metal splatter, which can conduct electricity in the presence of water. Additionally, the electric arc used in MIG welding produces a large amount of heat, which can pose a hazard to the welder and cause damage to the surrounding area.

How to Weld Cast Iron with MIG Welder – Best Tutorial with 2 Methods

A MIG welder is a device that uses a gas-powered electric arc to join metal pieces. Cast iron is a material that is commonly welded because it generates a lot of heat and frequently has dense welds. Here Weld FAQ provide how to weld cast iron with MIG welder, stay tuned to expand your knowledge!

What Gas for MIG Welding?

When MIG welding, use gas to keep the outside air from coming into touch with the hot arc and the welding material. The shielding gas also contributes to the ease of arc ignition, arc stability, welding spatter control, and excellent detail and aesthetic weld quality. There are many different types of MIG welding machines available, and they are categorized according to the kinds of gases and gas mixes that are permitted for welding. What gas for MIG welding? 

How to Store TIG Welding Rods to Ensure Perfect Weld?

Storage conditions

 The first thing to bear in mind is that these electrodes must be stored in dry, low-humidity settings in order to function effectively. To restore quality whenever the electrodes absorb moisture from the air, dry them right away. The weld will become porous and break if the electrodes absorb too much moisture. So check your storage if you see a decline in electrode arc performance….

How to choose right TIG Welding Rod?

Welding rods have the function of increasing the strength of the weld, and avoiding rust, so in TIG welding techniques, there are high requirements for the use of welding rods so that the technique is correct. In this article, weldfaq will share TIG welding rod types and How to choose right TIG welding rod.

 How to Setup TIG Welding for Beginners?

TIG welding, also known as Gas Tungsten Arc Welding (GTAW), is a type of welding that uses a non-consumable tungsten electrode to produce the weld. Here is a basic setup for TIG welding:

1. Power source
2. Tungsten electrode
3. Welding torch
4. Filler metal
5. Gas supply
6. Foot pedal or finger control
