2019年4月5日 · The silicon bronze rod’s lower melting point makes it ideal for joining together thin sheet metal, galvanized steel, and nuts and bolts, too. It’s nice for sheet metal work because the lower melting temps means less heat, which equals less warping when compared to TIG with, say, an ER70 rod.

2020年6月4日 · MIG brazing benefits. MIG brazing may not be a familiar process to many, but it has been around for years. Today, it is gaining popularity due to the benefits it can offer, especially with silicon bronze filler metal. Learn about MIG brazing, silicon bronze and how to properly set up your welding power source for this process. Questions and answers

2018年8月7日 · The selection of the right filler metal is critical in TIG welding aluminum. Most cast aluminum engine components are made from a casting alloy called A356. When welding aluminum, anything higher than 150 degrees Fahrenheit is considered a high-temperature application. To reduce the potential for cracking, choose a 4000-series filler metal that ...

2012年11月6日 · Oxides on aluminum TIG filler metal can be introduced directly into the weld puddle and lead to porosity. Oxides on MIG filler metals also cause problems, including an erratic arc, added resistance, sooting and poor feeding. And thicker oxide layers on aluminum base metals must be removed mechanically or face the risk of contaminating the weld.

2020年4月8日 · Most of the work I’ve done with plate and extrusions has been with 6XXX series aluminum — and 5356 filler rod is the best match for these alloys. 5XXX series aluminum is available in a wide range of thicknesses, from thin sheet to heavy plate, and either 5356 or 4043 filler rod can be used for these alloys.

2009年8月1日 · Learning to TIG aluminum. TIG welding aluminum doesn’t need to be intimidating. With a little practice — and some basic best practices to help beginning welders — you can produce the results you want. Follow our four steps below to practice and advance your TIG welding skills with aluminum. Step 1: Watch hand and torch placement

2020年4月3日 · 2. Welding aluminum in the wrong polarity/adjusting balance. This TIG weld (Figure 2A) was created with the machine’s polarity set on direct current electrode negative (DCEN). As you can see, the weld did not break down the aluminum oxide layer. The filler metal mixed in with the partially melted oxide, creating the contaminated bead seen here.

2009年8月13日 · If using a drag vs. a push technique (FIG. 3, below) on aluminum, you may get a sooty looking weld (FIG.2). The soot can be removed, but cutting the weld open will reveal pinholes where impurities are trapped in the weld. Aluminum builds up an oxide that needs to be removed before welding. Wire brushing is the most common method of cleaning ...
