4 Common Solvent Welding Mistakes and How to Avoid Them

4 Common Solvent Welding Mistakes and How to Avoid Them

Welding mistakes can be avoided when you put the right emphasis on the tricks to avoid them. As far as we know, surveys have concluded that half a million people get hurt by welding mistakes.

Therefore, solvent welding can be fatal if the right precautions are not in place. Besides the common problems and avoidance tricks, you should always have the right equipment. It includes safety glasses, gloves, boots, welding helmets, and hearing protection or cover.

Poor Preparation

This point relates to having limited knowledge, resources, and overall preparation to carry out solvent welding tasks. You will be poorly prepared when you lack investment in the welding project plan.

Poor preparation leads to injuries and more accidents on-site.


You can avoid poor preparation with the right equipment like LESSO solvent weld fittings. In addition to that, ensure no dirt, dust, or crumbs are left behind after the welding job.

Hire an inspector to carry out that job before, during, and after the completion of solvent welding.

The inspector must also check whether the grinding of metal is on point before its use. They should know that metals like Aluminium must be cleaned thoroughly. However, welding experts can work around ferrous metals without prior cleaning.

Not Having Appropriate Practice

Simply reading books on welding and the chiseling of metal pieces is not enough. The real job is when experts perform solvent welding jobs with certification and experience.

We understand that theoretical knowledge forms the base of expertise in welding. But without hands-on experience, it is all a waste. And if you are on a sensitive and complex welding project, it’s a common mistake to hire amateurs.


You need to work with experienced people on complex welding projects, especially when a large sum of money is involved. Or, enable your employees or welding professionals to regularly practice on raw material or metal pieces.

Train them in different stages of solvent welding. It helps them to find their expertise and specialization in welding tasks. And that’s how you assign and allot professional welders to particular projects.

Not Performing Maintenance Tasks

Another most common solvent welding mistake is this one. People and manufacturers often avoid maintenance tasks to hedge the cost. But it strikes back, demanding more money for maintenance in later years as depreciation also takes place.

You need to know that welding machines, tools, and other accessories are prone to regular wear and tear. If your company or you (individually) are using a welding gun, avoiding maintenance is not even a choice anymore. Maintenance is essential.

Without maintenance, the welding machine or gun won’t perform tasks at its full potential. You will end up buying a new one, probably more costly this time.


Hire professional welders or technicians. They know how to look after welding machines and tools regularly. Or, train your workers to look after their tools daily. Tell them how it’s important for the welders to sharpen, chisel, or oil their tools.

It helps increase the efficiency, productivity, and longevity of each tool and machine.

Choosing Wrong Wires or Gun Sizes

Regardless of the welding method, the wire and the welding machine gun size should be appropriate.

Some professionals think that a single wire can work on multiple welding projects. That assumption is wrong and miscalculated even with the choice of welding gun size.


Have ample knowledge of welding electrodes and wires. Know which wire is best for carrying out different welding methods. Similarly, know when to use a welding gun with low or high amperage.
