Flat plastic sheets can be used in a lot of creative ways, particularly because they can be welded together much like metal. If you want your welding results to turn out great, there are a couple of strategies to consider before you begin fabricating.
Use Sheets with Similar Properties
If you want flat plastic sheets taking to other plastic sheets correctly throughout your welds, then consider using sheets with the same properties. Then you can get more uniform results without you needing to adjust your welding techniques.
You'll know how all of your flat plastic sheets are going to take to welding because you're familiar with their specific properties. Whereas if you tried welding thick flat plastic sheets with thinner pieces, there are more variables at play, and that can hinder the welding results you're able to achieve at the end.
Weld Enough Joints
In order for your flat plastic sheets to stay conjoined, you need to make sure you weld enough joints. If you don't, it's more likely that sections of the plastic sheets will come apart and then ruin the project they're being used in.
The number of joints you need to weld depends on the size of the flat plastic sheets you're working with and how the sheets are going to be used in a particular setting. For instance, if the flat plastic sheets will experience ample movement and vibration, welding a lot of joints can better protect these sheets from coming apart.
Use Test Kits to Properly Identify Unknown Plastic Varieties
There are many different varieties available for flat plastic sheeting. If you already have some in your possession but aren't sure what plastic variety they feature, you'll want to have them tested. You can purchase test kits yourself to find out what particular plastic variety you'll be welding.
The type of plastic does matter for the welder you choose and the techniques you observe when conjoining plastic sheets. These tests come with instructions so it shouldn't be hard to conduct them yourself and find out what plastic the sheets feature. Then you can weld with more direction and strategy.
Combining flat plastic sheets together may be needed, whether it's to increase the overall size of these plastics or to form unique shapes. As long as you go through and review proper welding protocols with this material, you can stay safe and perform better when welding.
