Causes of Porosity in Submerged Arc Welds

Submerged arc welding is typically done automatically, meaning it is not done by hand, but rather set up as hard automation.  The operator simply controls the welding machine and torch position to obtain the desired results.  Typically,the system is run by an operator, not a welder.  So when problems come up, the operator may not […]

7 Ways to Eliminate Porosity in Your Welds

Porosity is a weld discontinuity that is not as detrimental to structural integrity as cracks, undercut, overlap and lack of fusion. However, it is unsightly and when painted it becomes an eye sore. Because it does not have sharp ends, porosity does not propagate like a crack. The reason for limits to the amount of […]

10 Types of Welding Discontinuities Explained

Not all discontinuities are defects

Cracks can lead to catastrophic failure in a relative short amount of time.

Not all weld discontinuities are weld defects, but all weld defects are discontinuities. Understanding the difference will let you know if you need to scrap a part, repair it or simply add more weld. There are many codes depending on what type of product you are welding on. The codes are used as guidelines by […]

How to Qualify a WPS for Welding Stainless to Mild Steel using AWS D1.6

Macroetch locations for welding procedure qualification of fillet welds.

It is very common to weld stainless steel to mild steel.  But, when it comes to qualifying a welding procedure it can be somewhat confusing.  Do you follow AWS D1.1 (Steel) or do you following AWS D1.6 (Stainless Steel)?   Or is there another code or standard you should use? The answer to this question is […]

How to Weld Galvanized Steel

Galvanizing is the application of a zinc coating to a ferrous material. It is done to prevent, or at the very least delay corrosion. The zinc coating can be applied in many different ways including but not limited to hot-dipping, metal spray and electrodeposition.  Similar to galvanized steel is galvanneal steel.  Galvanneal is the process […]

Characteristics of Aluminum That Affect Weldability

If you have welded aluminum you know that it behaves considerably different than steel.  Other than the strength difference and general appearance, there are four physical characteristics of aluminum that make it weld completely different than steel.  These are: High thermal conductivity High solidification shrinkage High hydrogen solubility Oxide coating When welding aluminum it is […]
