How to stop pinholes when TIG welding

-

TIG welding is a great way to join metals and it produces beautiful welds. However, if you are not careful, pinholes may appear in the weld path of TIG welding.

How to stop pinholes when TIG welding?The best way to prevent pinholes when TIG welding is to avoid some common causes, such as

✱ The shielding gas does not protect the bead

✱ Part of the weld is contaminated

✱ Amperage is set too high

✱Welding arc is too long

✱You are pushing the bead too fast

✱The current cuts off too quickly at the end of the weld


How to stop pinholes when TIG welding


Any one of these problems is easy to fix if you know what to look for.

Gas problems

The high temperatures in TIG welding can cause the weld to oxidize in the air. The torch provides a shielding gas that protects the weld from oxygen when it is extremely hot. If the gas is not distributed correctly, pinholes and cracks can result. What can destroy the shielding gas?

The gas is not turned on.

We've all done this before. If the gas is not turned on, the arc will produce more sparks and spatter. Make sure the gas is turned on when you start welding.

Wrong flashlight angle.

The torch should be held vertically to allow the gas to flow directly over the arc and weld. If the torch is tilted too far away, the shielding gas will not cover the arc and the weld will be unprotected. This can lead to pitting and cracking of the joint. The effect is the same as not using gas at all.

  In the realm of metal fabrication,   arc welding   stands as one of the most fundamental and widely used techniques. It encompasses various methods, each offering unique advantages and applications. In this comprehensive guide, we delve into the different types of arc welding techniques, their mechanisms, applications, and notable characteristics. Arc welding is a fusion  welding process  that utilizes an electric arc to melt and join metals. The arc is created between an electrode and the workpiece, generating intense heat that melts the base metals, forming a strong bond upon cooling. This versatile method finds extensive use across industries, including construction, automotive, aerospace, and manufacturing. Shielded Metal Arc Welding (SMAW) Shielded Metal Arc Welding, commonly known as stick welding, is one of the oldest and most straightforward arc welding techniques. It involves a consumable electrode coated in flux, which provides a shielding gas and forms a slag to protect th
