Whether you are a DIYer who stick welds only a few times a year or a professional welder who welds every day, one thing is certain: Stick welding requires a lot of skill. It also requires some know-how about stick electrodes also called welding rods. Because variables such as storage techniques, electrode diameter and flux composition all contribute to stick electrode selection and performance, arming yourself with some basic knowledge can help you minimize confusion and better ensure stick welding success. Hundreds, if not thousands, of stick electrodes exist, but the most popular are mild steel electrodes, which fall into the American Welding Society AWS classification A5. These include the , , , , , and electrodes.

Welding ElectrodesVIDEO ON THE TOPIC: How to Buy and Store Stick Welding Rods long term
Storage of electrodes in cardboard boxes requires humidity and temperature controlled storage areas. Plastic boxes require storage conditions suitable to cardboard boxes 2c. No temperature and humidity requirements are applicable for electrodes in Linc-Can Mini-Pack and Sahara ReadyPacks, providing that vacuum seal is present in undamaged packs.
Handling 3a. Re-drying and subsequential holding, as recommended in table 1, is required for products in the following conditions rutile electrodes, being humidified for any reason; basic low hydrogen electrodes in cardboard boxes; basic low hydrogen electrodes, returned from shop floor or damaged Sahara ReadyPacks, Mini-Pack or Linc Can; stainless steel and Ni-base electrodes after long and unknown storage conditions deviating from recommendations ; Wearshield electrodes in plastic PE boxes, stored for more than 1 year under conditions as described under section 2a.
Electrodes in Sahara ReadyPack and Linc-Can can be used without re-drying, providing that vacuum or seal is present in the undamaged packaging. Once opened Linc-Cans should be closed during welding operations using the plastic lid that is supplied with the tin. Electrodes in Mini-Pack can be used without re-drying, provided that the vacuum is present in the undamaged packaging.
Covered electrodes that have suffered from serious water and moisture contamination, or have been exposed to the atmosphere over long periods of time cannot be restored in their original condition and should be discarded.
Redrying of electrodes should be carried out by taking them out of the packaging and place the electrodes in approx. Storing and handling instructions for stick electrodes.

Stainless Steel 309 Welding Electrode
The arc and the weld pool are shielded by gases and slags which result from the decomposition of the electrode coating. Application Widely used in the fabricating industries for the construction and repair of plain carbon and low alloy steels. Stainless steel, inconel, nickel and cast iron electrodes are also commonly used, as are surfacing type electrodes for the building up of wear resistant surfaces. The equipment is of initial low cost, and the process is flexible and safe to use. Good ventilation and protective clothing is essential. Open circuit voltage must be high enough to initiate the arc, volts , therefore a drooping or constant current power source would be appropriate. Electrode holder Designed to insulate the operator from the currents and voltages used during welding and to enable the electrode to be firmly clamped in position, to facilitate access to joints.

Part 1 Part 3 Part 4 Part 5. The previous article, Part 1 , dealt with the cellulosic and rutile electrodes. This article will cover the basic, iron powder and acid electrodes. Also deoxidants such as ferro-manganese, ferro-silicon and ferro-titanium are added to provide de-oxidation of the weld pool. Other alloying elements such as ferro-chromium, ferro-molybdenum or ferro-nickel may be added to provide an alloy steel deposit. The gas shield from basic electrodes is not as efficient as that from the rutile or cellulosic types and it is necessary to maintain a constant short arc if porosity from atmospheric contamination is not to be a problem. The electrodes are particularly sensitive to start porosity because of the length of time taken to establish an efficient protective shield. An essential part of welder training is familiarisation with the technique of starting the weld ahead of the required start position and moving back before proceeding in the direction of welding. The penetration characteristics of basic electrodes are similar to those of rutile electrodes although the surface finish is not as good. The slag cover is heavier than rutile electrodes but is easily controlled, enabling the electrodes to be used in all positions.

Published on December 17, December 1, SMAW or stick electrodes are consumable, meaning they become part of the weld, while TIG electrodes are non-consumable as they do not melt and become part of the weld, requiring the use of a welding rod. Electrode selection is critical to ease of cleanup, weld strength, bead quality and for minimizing any spatter. Electrodes need to be stored in a moisture-free environment and carefully removed from any package follow the directions to avoid damage. When molten metal is exposed to air, it absorbs oxygen and nitrogen, and becomes brittle or is otherwise adversely affected. A slag cover is needed to protect molten or solidifying weld metal from the atmosphere. This cover can be obtained from the electrode coating.
While there is no such thing as the perfect welding process for stainless steel, keeping some key considerations in mind when selecting the process and filler metal can help ensure success and cost savings. Stainless steel continues to gain popularity in applications across the fabrication industry, mainly thanks to its corrosion resistance, strength, and toughness. Compared to mild steel, however, the material poses some welding challenges, especially for less experienced welders.
