Finally, with the exception of grade 1144, resulfurized steels are generally not sold to mechanical property requirements. Welding implies mechanical property performance. We have seen 1215 welded using an inertial or friction welding process. But these welds are  usually not subject to mechanical loads, merely attachment. Here’s a video of a friction weld process for truck axles from Thompson Friction Welding in the UK. Want a second opinion? Dave Barton at Lincoln Electric hosts a column   Barton’s Q&A in Welding Magazine published by Penton.  The second question in this column deals with welding 12L14. Think of weldability and machinability as two sides of the material coin. Heads it machines well, welds lousy, Tails... You can usually win on one, but at the expense of the other. If you need to weld, a low carbon plain carbon steel is your best bet.

Any type of arc welding of resulfurized steels is generally avoided. This post will give you some  reasons why. Resulfurized steels are free machining steels. This includes steel grades in the 11XX and 12XX series,  such as 1215, 12L14,  1117, 1137, and 1144. These steels contain sulfur and may contain lead. These two elements will create low melting temperature constituents that will cause cracks. Here are 3 reasons not to weld resulfurized free machining steels:

To buy engine parts for your County Line, like an air filter, oil filter, fuel filter, spark plug, tune-up kit, or carburetor parts, you will likely need to search separately on PartsTree for your engine model. On County Line equipment, the engine model and specification ("spec") numbers, as well as serial number and sometimes type and code, are often stamped above the muffler, by the spark plug, or near the overhead valve cover.

Your County Line equipment has a factory model number and serial number on a sticker-like label or metallic tag attached to the unit in a place away from moving parts (usually near the handle, under the seat, or on the side of the unit). The best way to buy repair parts for your County Line is to begin by searching for your County Line model number on PartsTree and use the OEM County Line parts diagrams to find the parts that fit exactly like the originals from the County Line factory. When you locate your County Line model tag, take a picture for future repair parts needs.
