Working with sheet metal, especially the thin ones, is such a daunting task for amateur and inexperienced builders or welders. Nowadays, there are many different ways for assembling sheet metal, but the principle behind it remains the same. Sheet metal assembly, regardless of its method, refers to the process of fastening or combining two or more metal components to come up with a single output.
Any sheet metal assembly is always dependent on the components that are being used and assembled. For instance, the approach in melting or joining pieces of metal such as steel and copper is different from thin aluminum and other plated components.
Welding is the most popular way of fabricating or assembling sheet metal. Over the years, the advancement in the metals industry has paved the way to a number of welding methods and equipment. Depending on what you want to achieve on your project, welders can now carry out various sheet metal assembly techniques such as arc welding, gas welding and many others. Each of these welding techniques has its own features and uses in particular industrial applications.
Arc welding, for example, makes use of an electric arc. It utilizes heat of an electric arc to combine metal. Direct or alternating current can either be used depending on the components to be welded. In gas welding technique, meanwhile, burning gas is used to create heat. Gas welders may use propane, oxyacetylene and oxy-propane torches.
Aside from welding, there are other ways to combine sheet metal components. If you don't know how to solder, you can undertake simple assembly routes such as riveting, bolting and screwing to assemble sheet metal. In bolting and screwing, stainless steel screws, either oval head or pan head, are often used to join metal sheets.
For this assembly task, you will need tools such as drill, twist-drill bits, scratch awl, center punch, and measuring equipment. Snips for cutting the sheet metal, as well as a pop-rivet tool and pop rivets, are required to join the pieces of sheet metal together.
Here are some useful tips that will help you save time and money in your sheet metal fabricating job:
1. Keeping your storage and work area as organized as possible will help you complete the job faster. It's totally uninspiring to work in a cluttered room. Keep your tools in shelves and remove rags, paper and other things in the area before working. This will help you find the equipment more easily when needed.
2. If you're on a tight budget, making pattern materials out of newspaper or cardboard is a good idea, particularly if you're just making a one-time prototype.
3. To maintain the good condition of your shears, dip them in coffee that is kept full of oil then wipe them down using a clothe. By doing so, you will keep the sharpness of your shears.
4. Check the hoses and connectors on a regular basis to determine if they have leaks Use a soapy solution for that. If you find any leakage, better replace them than patching them up with electric or duct tape.
5. Having an organized and stable work platform is also essential to accomplish the desired layout of the sheet metal that you're working on.
6. Novice and veteran metal professionals should invest in quality pairs of leather gloves. Most sheet metal materials these days come with a thin coating of oil to prevent rust and oxidation from forming on the metal. A good pair of gloves will keep the oily surfaces from your bare hands.
7. Your work area should also have proper ventilation. Working with metal, especially when welding, generates fumes that can harm you and hamper your work process.
8. When fabricating a metal, prepare the surface that needs to be weld. Electricity travels more efficiently if the metal is clean. Remove all the rust and use a wire brush to clean the surface.
9. Before even thinking of trimming a sheet metal, measure it repeatedly. Do not hesitate to check it again and again.
10. Always keep your transfer pencils sharp. Nothing can spoil a pattern transfer to sheet metal worse than a too broad of a line.
