Explore a variety of welding-related topics that don’t quite fit into the main categories—but are just as valuable. From unique project ideas and industry news to creative applications, community stories, and beyond, this section is your go-to for all the extras that fuel inspiration and broaden your welding knowledge.
If you’re firing up an oxy-acetylene torch, the flame you choose can change the chemistry, heat concentration, appearance, and strength of the finished joint. Understanding the types of gas welding flames and their applications helps you avoid oxidation, carbon pickup,…
Plastic-to-wood repairs fail for a simple reason: the two materials behave differently. Wood is porous and moves as moisture changes, while plastic may be smooth, flexible, solvent-sensitive, or difficult for adhesive to wet. The strongest glue for plastic on wood…
Turning welding skills into extra cash started for me with a few small welding projects to make money in my garage. I learned quickly that the most profitable jobs are not always the largest or most complicated. Simple products such…
Old saw blades can be useful shop material, but they should never become angle-grinder attachments. Toothed blades can snag, kick back, and defeat the protection built into a grinder’s guard. The safer approach is to use a wheel approved for…
Bonding aluminum to steel is harder than joining two pieces of the same metal. The surfaces oxidize differently, aluminum expands more than steel as temperatures change, and ordinary fusion welding can create brittle compounds at the joint. For a small,…
Rust-Oleum can protect rusted steel, but the result depends on choosing the right product and preparing the surface correctly. You still need to remove loose scale, grease, failed paint, and any metal that has lost too much thickness. If the…
Calculating weld thickness starts by naming the dimension you actually need. For a fillet weld, that usually means the leg size and effective throat. For a groove weld, it means the effective penetration provided by the joint detail. The final…
A homemade bottle-jack press can handle small bearing, bushing, light-forming, and assembly work, but it can also store enough force to eject tooling or tear an unengineered frame apart. The safer approach is to treat the project as machine design:…
A leaking HVAC copper line can turn a small repair into a costly system problem fast. Brazing produces a durable refrigerant-line joint, but it also involves an open flame, compressed gas, high system pressures, and refrigerant-handling rules. Clean preparation, a…
Brazing HVAC copper lines can feel high-pressure because one poor joint can waste time, refrigerant, and money. Reliable work comes from verifying the equipment instructions first, preparing clean copper, flowing dry nitrogen, heating the entire joint evenly, selecting the correct…
