- A car’s fenders are among its most abused parts. Small rocks and road dirt, not to mention the road salt that eats away at them all winter long, continually assault the paint on the fender’s wheel openings. Over time, this abuse will eventually expose bare metal and lead to rust. Rust is metal’s natural enemy, and will eat away the fender’s metal before you know it. Fear not: Cutting out the rusted portion and replacing it with a metal patch panel can save that fender.
Single-Ply Flat Roofing Weld Techniques
Single-ply flat roofing membranes provide an economical and durable alternative to traditional asphalt roofs. As with metals that are conjoined, these roofing membranes require a permanent seal to prevent leakage and ensure that the roof remains intact. This generally requires some type of welding technique specifically designed for use with these roofs or similar materials.
Welding Techniques Using a DC Machine
Electric arc welding machines can employ either direct current, or DC, or alternating current, AC. For most general purpose welding of steel, DC welders offer better performance and ease of use. AC welders are superior when welding steel that’s become magnetized. When welding with DC current, there are certain basic techniques to follow if you want a solid welded joint. When welding, wear appropriate protective clothing and face shielding.
Metal Welding Techniques
Welding, the process of joining metals with the use of heat and electricity, encompasses a variety of techniques. The type of metal and the requirements of the weld determine which technique is used. Like many skills, proficiency in welding is learned in progressive steps of increasing difficulty. Simple stick welding is fairly easy to learn, but more advanced techniques require practice, patience and the right equipment.
Welding Spatter Clean Up Techniques
A skilled welder will take steps to minimize spatter caused during the welding process. However, even skilled welders will eventually have a spatter or two to take care of after a welding project. Fortunately, you can clean up a messy weld without taking days to complete the project. With a little hard work, you too can have clean welds, even if you are not a welding expert.
Boat Skeg Welding Techniques
A boat skeg is the extension of the keel of a small craft designed to improve steering. Boat motor skegs are easily damaged if they hit objects and can break off. These aluminum skegs can be repaired with gas metal arc welding, using a few basic techniques.
Welding Precautions
Welding is an industrial process that uses heat and electricity to join two pieces of metal. Because of the intensity of the power and heat used, welding creates a number of operating hazards. Always keep a first-aid kit on hand when welding. Using the proper safety precautions will protect welders from shocks, burns and long-term health risks from exposure to welding fumes.
Welding Joint Types
The weld joint is necessary to connect two or more welded parts to provide adequate strength and long-term safety. When you're choosing a welding joint for your project, consider whether pressure will be applied to the joined area and whether that pressure is constant or intermittent. The joint efficiency is also important (the ratio of the strength of the joint compared to the strength of the welded metal). There are four main types of welding joints.
Welding Gouging Techniques & Equipment
Gouging is a method used to melt or fuse metals in a narrow groove using compressed air. It is commonly used to weld joints together.
Pulse Welding Tips
Pulse welding is a process that makes welding easier with the same quality results. This method will most likely be attractive to any welder, but dealing with new equipment and techniques is not. If welders keep certain things in mind in relation to equipment, setup and procedure, they can successfully use pulse welding.
Different Flanges
Flanges may take many forms: they may be strengthening ribs, like the flange of an I-beam, or guides, like the flange of a train's wheel. However, one of the principal uses of the word "flange" refers to its use in plumbing as a means of joining pipes, valves or pumps. Typically, flanges are fixed to pipework systems with bolts, by soldering or through a combination of the two techniques.
Oxy Welding Tips
Oxygen-acetylene welding is a welding technique utilizing these two gases to produce a flame able to weld and even cut relatively thick plate steel. This technique requires specific types of welding tips that produce certain properties in the flame. These tips can be categorized into three general categories; single flame, multiple flame and specialty flame.
- Aluminum Fabrication Tips
Products made of aluminum are present everywhere in modern life. For example, aircraft, automobiles, marine, electricity, electronics, construction and the food industry use aluminum fabrications. Because aluminum is so versatile and malleable, it easily takes shape using different metalworking techniques, including casting, rolling, extruding, drawing, welding, machining and forging. Aluminum is a soft, lightweight, chemically-reactive metal that requires special techniques for fabrication.
Types of Welding & Techniques
- Welding is, in short, an art form. There are many different types of welding requiring different skill levels. Most beginners work with Mig welding or Arc welding, which are both relatively easy to work with. Tig welding, on the other hand, is a much more elegant style of welding that produces better welds and allows you to weld aluminum easier than other methods of welding. Tig welding should be left to the professionals who have the skills and resources necessary to purchase a Tig welder, which can cost thousands of dollars.
- When metal is torn, or breaks, welding is the best way to fix the metal. Welding is reliable, strong and can sometimes give a metal piece a whole new life. Wire welding is a technical practice that can take years to learn properly. It takes a steady hand, and a calm technique. Learning some of the basics, and learning the tips that will keep you safe, is essential to becoming a good welder.
