90% of the bulk tanks are polyethylene. It is probably the easiest material to weld there is. The process is heat dependent. Too much, and the plastic changes structure, blackens and oxidizes, loosing strength. too little and the material really is not joined. Deep root welding it important in this case to prevent weld failure. Cutting a groove with a sharp utility knife if the material is 1/4" thick, or thicker. is needed to assure depth of weld penetration. The filler rod is used to both stir and fill at the same time. The plastic stays hot a long time, and will burn, and stick to your skin making a real serious 3rd degree burn, don't go there. Practice on similar material if you can, and be patient. It is no harder than working with a oxy acetylene setup welding steel. The tool is almost always plunged into the depth of the weld . Watch some YouTube on it before starting. Make sure the stress that caused the cracking is eliminated, the weld will not likely be stronger than the original. Once you develop some heat control, and fill stability go at it. Jim

Today's Featured Article - Tractor Hydraulics - The Basics - by Curtis Von Fange. Hydraulics was one of the greatest inventions for helping man compound the work he can do. It’s amazing how a little floor jack can lift tons and tons of weight with just the flick of a handle. What’s even more amazing is that all the principals of hydraulic theory can be wrapped up in such a small package. This same package applies to any hydraulic system from the largest bulldozer to the oldest and smallest tractor. This short series will take a look at the basic layout of a simple hydraul
