What is stick welding?

Posted on

Stick welding is also known as shielded Metal Arc welding (SMAW) or manual metal arc welding(MMA) . Stick welding is an arc welding process in which coalescence of metals is produced by heat from an electric arc that is maintained between the tip of a consumable covered electrode and the surface of the base metal in the joint being welded.

Stick, the most basic of welding processes, offers the easiest option for joining steel and other metals. Stick welding power sources deliver inexpensive options for welding versatility, portability and reliability.

Stick welders are used in small welding shop, by the homeowner, by the farmer for repair of equipment – as well as industrial fabrication applications, structural steel erection and other commercial metals joining. All common materials can be welded with a stick machine, be sure to select the appropriate stick electrode for the material being welded.
Advantages of stick welding are it is simple to use, inexpensive and portable. Auxiliary gas shielding or granular flux is not required. It can be used in areas of limited access. The process is suitable for most of the commonly used metals and alloys. The welding current used for stick welding may be either alternating current or direct current depending on the electrode being used. Direct current is the most common current choice for stick welding. The current flows in one direction only and has many advantages over alternating current for the stick process. These advantages include: fewer arc outages, less spatter, easier arc starting, less sticking and better control in out-of-position welds.
Alternating current is an electrical current that has both a positive and a negative half-cycle value alternately. Current flows in a specific direction for one half-cycle stops at the zero line and then reverse direction of flow the next half-cycle at regular intervals. The AC sine wave represents the current flow as it builds in amount and time in the positive direction and then decreases in value and finally reaches zero.
DC welding offers more advantages than AC for most stick applications, including: easier starts, fewer arc outages and sticking, less spatter/better looking welds; easier vertical up and overhead welding. A 225 to 300 amp machine handles almost anything the average person will encounter, as most stick welding procedures require 200 amps or less. To weld material thicker than 3/8 in, simply make multiple passes-this is what professionals` do, even when welding on 1 in structural steel.

1.All nylon construction resists salt water, weak acids, gasoline, alcohol, oil, grease, and common solvents. Molded of type nylon 6. Flammability classification 94V-2: temperature index 125°C
2.No disassembly required. Instead, the installer simply pushes the conduit or tubing onto the ferrule, tightening the domed sealing nut. The completed assembly can then be secured in the chassis by the locknut (or first secure the connector into a NPT threaded hole)
3.No threading of the conduit or tubing required to install, eliminating the possibility of cutting the conduit and creating leak paths. Applications: HVAC equipment; Machine tools; Marine equipment; Motors and controls; Printing equipment; Pumps; Refrigeration equipment; Transformer connections; Outdoor lighting
4.Complete conduit/connector system is reusable. Conduit will not wind tight onto the connector during assembly and can be easily removed by pulling while turning in a clockwise direction
5.Suitable for indoor/outdoor use; for original equipment manufacturers or field installers. 0 Ring and steel locknut included
