Welding Hot Rolled vs Cold Rolled Steel

Both hot rolled and cold rolled steels can easily be welded.  However, there are differences between the two that will impact which you choose to use.  Making this choice depends on several factors such as strength, surface finish, dimensional accuracy and cost.   To understand the difference between hot rolled and cold rolled steel and how […]

3 Keys to Troubleshooting Welding Problems

Troubleshooting of welds and other welding problems increases costs in welding, causes delays and affects weld quality.  Even a moderate understanding of welding problems, their symptoms, causes and potential solutions can help tremendously.  The more informed you are the better. To successfully troubleshoot and fix welding discontinuities, welding defects and other welding problems we need […]

3 Reasons Why You Need to Make Smaller Welds

Bigger is not always better, at least not in welding.  Making welds bigger than they need to be is not only wasteful and costly, but can cause other problems such as distortion and premature failure. Below are 3 reasons why you may need to pay close attention to your weld sizes.  1. Bigger welds cost […]

5 Common Mistakes Made When Estimating Welding Costs

Read this before you bid on a welding contract

When bidding jobs several fabricators end up calculating their costs associated with welding and then double that number to be safe. In some cases, that isn’t even enough. It is important to have a clear understating of how to translate the amount of welding to be done to actual manufacturing costs. One of the biggest challenges is that rework and overwelding is […]

Rule of Thumb for Fillet Weld Sizes

Many fabricators can lower their welding costs significantly if they paid close attention to weld sizes.  If a print calls for a ¼” fillet weld and in production you make a 5/16” fillet weld, you are overwelding by 56%!  If the print calls for a 3/16” fillet, the 5/16” fillet weld you deposit would be […]

Steps to determine if welding preheat can be eliminated?

Testing the effects of preheat in small parts and assuming it will be the same on large sections is a mistake.

As discussed in our previous article, and many times in the last 50 or so, preheat is necessary in steel welding to control the cooling rate.  More specifically, preheat is used to slow the cooling rate down in order to prevent excessive hardness in the heat affected zone (HAZ) which  can lead to cracking.   Before […]

Why More Customers are Requiring Qualified Welding procedures

If you own or work at a job shop you may have noticed an increase in the number of customers that require the use of qualified welding procedures to build their products. Some fabricators are even getting this request from long time customers who never required them in the past. So why is this? The […]

The Outrageous Cost of Poor Fit Up in Welding Operations

You will cringe when you read this

In a perfect world parts would fit together perfectly every time.  However, as we all know, this isn’t the case.  We mostly think of poor fit up as something that annoys welders but which they can compensate for.  But the reality is it can have tremendous impact on your bottom line.  Or, in many cases, […]

How to Determine Acceptable Weld Quality

Certain industries that involve welding of their products have very strict quality standards to ensure the production of sound welds.  Many others however, do not.  They simply weld and unless one of their products fails they don’t pay special attention to welding procedures, detailed inspection of welds or testing the skill (performance) of their welders. […]

Danger of Using the Wrong Shielding Gas for GMAW

In our previous article we mentioned that a customer was inquiring about running their 98% argon / 2% carbon dioxide (98/2) shielding gas on mild steel.  This gas is used on stainless as it maintains the amount of reactive gas (in this case CO2) under 3%.   Our quick answer was “yes, you can weld carbon […]
