Welders wedge is the primary welding technique that is employed by Layfield in the field and in the welders fitting tools shop. Layfield’s core competencies are the welding of thermoplastic sheets in field construction. One of the techniques used by Layfield is thermal wedge welding. Welder wedges machines that use a sort of heated element just to fuse the thermoplastic sheet materials. The wedge welders are the automatic machines that run between the two sheets of material, which are overlapped.
Next the welder heats that interface just between those materials and then starts to press the materials together to form a lap weld as well. Then the thermoplastic materials are already fused at the molecular level even without any addition of any solvents or glues. Every brand of welder should have a slightly different arrangement of overlaps, wedges, and the pressure rollers. Layfield has a number of various wedge welder types to address the welding situation.
The Ability To Field The Wedge
Wedge welding is one of the most commonly performed on HDPE sheet materials; however the Layfield has all the skills just to weld most of the thermoplastic geo membrane materials. One of the unique efficiency is to have the ability to field the wedge weld PVC materials at any thickness. Even the film welding techniques are also using specialized equipments as well. Along with these special welders they could routinely weld such sheeting much thin. Nonwoven geo textiles could be also welded with the wedge welding skills and however this kind of welding tacks the geotextile together only. For a better geotextile seams Layfield provides field and welders fitting tools shop geotextile sewing services as well.
The Uses Of Welders Wedge
Welders wedge as a basic technique for the production welding in the field of installations. The wedge welders run at continuous speed that mostly depends on the material basically and between overlapped and, clean material. Actually welders are exclusively used for the very straight run welds. A welder could not be used for a detail work or for the curves. The most importantly the wedge welded job would almost require the finishing work all the time. For the finishing work you need to see some of the technical notes related to bonding seam welding and the extrusion welding.
Types Of The Welders Wedge
Basically there are two wedge welders’ arrangements. One of these are the solid wedge and the second one is the split wedge.
The solid wedge that is used for the thin film materials and it produces a weld not less than 25 mm in width that is fully bonded. This type of wedge welds is generally tested that is known as an air lance test.
The Split Wedge Welder
Second one, the split wedge welder that is more commonly used on the thicker materials than the solid wedge. The split wedge welds basically have the tracks in between them with a channel. And at the completion of weld this channel is completely sealed at both the ends and this is pressurized with air. And this type of air pressure test provides a complete non-destructive indication of continuity and seam integrity. The welders wedge is also tested by using a specific destructive testing.
The Field Destructive Testing
A complete crew that is equipped with the field for the field destructive testing. The welds are tested in peel and in shear. This shear testing is a basic test to identify the strength that is across a weld while peel and the testing are generally used to confirm the weld quality. Usually the Peel tests are performed on both the sides of a welders wedge will be available in welders fitting tools shop that is also called the left and right peel.
