Abstract: This invention relates to a gas shielded-type coated arc welding electrode, more particularly to the coated electrode consisting of a mild steel core and coating material which comprises 20 - 40% organic material by weight of a total coating material, and 5 - 25% anhydrous sodium silicate by weight of said of organic material wherein the molar ratio of SiO.sub.2 /Na.sub.2 O within said of anhydrous sodium silicate is 2.5 - 3.5. Such an electrode displays improved coating material moisture resistance and usability.

Abstract: The present invention relates to a coated welding electrode containing at least 0.5% of Cr based on the total weight of the welding electrode and comprising a metal core and a coating flux composition. In this welding electrode, the content of Na and K components in the coating flux calculated as (Na.sub.2 O + K.sub.2 O) is reduced below 1% based on the total weight of the coating flux composition, whereby amounts of fumes generated at the welding step, especially the amount of toxic soluble Cr, are suppressed and minimized.

Abstract: An improved welding electrode for producing weld metal having low amounts of hydrogen therein so that hydrogen-assisted cracking in the weld zone is minimized. This is especially beneficial for welding high strength steels having tensile strengths of about 70,000 psi and above. The electrode has a filler wire core and a flux covering of predetermined constituents and low moisture levels such as below about 0.6 percent. The flux is bound together with a binder of hydrolyzed organic silicate (silica) which makes no substantial contribution to the moisture level of the covering and which also makes the covering resistant to hygroscopic moisture pickup before the electrode is used for welding. Thus, this binder minimizes the amount of hydrogen from any moisture in the covering which may be introduced into the weld metal during welding. Additionally, the flux covering contains a source of barium or cesium in an amount effective to reduce the slag/metal reaction temperature during welding.

Abstract: An electrode for and method of welding cast iron and the like metals utilizing a 99% nickel rod in the presence of an alloying flux containing large amounts (30 to 60%) of iron plus manganese and carbon to yield a weld metal having the general composition: Nickel 60-85%, Iron 15-40%, Manganese 1.5-5%, Carbon 1-3% and Silicon 0.25-2%. The flux is preferably present as a rod coating and comprises from about 40% to about 60% of the weight of the composite coated rod. The coated rod can be used in any generally excepted welding technique including the use of alternating current, direct current straight polarity or direct current reverse polarity welding operations.

Abstract: A coating composition for a coated electrode for arc welding comprising 3 to 30% of fibrous mineral, 2 to 12% of crystalline cellulose, with the balance being at least one of a slag forming agent, an arc stabilizing agent, a deoxidizing agent and an alloying agent.

Abstract: A method of making flux-covered welding electrodes which are resistant to moisture absorption wherein untreated covered electrodes are treated with a dilute aqueous dispersion of at least one material taken from the class of silicon bearing materials consisting of colloidal amorphous solid silicas, quaternary ammonium colloidal silica sols and soluble silicates of lithium and potassium.

Abstract: Silanol containing organopolysiloxane resins, especially useful as release resins, prepared by the acetone-water hydrolysis of an organohalosilane blend consisting essentially of about 60 mole percent methyltrichlorosilane, 35 mole percent phenyltrichlorosilane and about 5 mole percent dimethyldichlorosilane, are provided. Cooking utensils, particularly baking utensils coated with the same are also provided.

Abstract: Directed to a welding flux and covered welding electrodes, and, more particularly, to covered electrodes having a nickel-chromium-iron alloy core and a special flux coating or covering, which electrode is capable of joining similar and dissimilar metals and which produces, in all positions, sound welds free from cracking and porosity and deposits having excellent corrosion resistance.

Abstract: Nickel-chromium-silicon steel electrode for arc welding provides maraging stainless steel weld deposits having desirable strength, toughness and corrosion resistance in age-hardened condition. Electrode arc can be shielded with inert gas or with lime-cryolite-titania flux containing specially controlled proportions of manganese.
