Shielded metal arc welding (SMAW), also known as manual metal arc welding (MMA or MMAW), flux shielded arc welding [1] or informally as stick welding, is a manual arc welding process that uses a consumable electrode covered with a flux to lay the weld.
Technical-Vocational Education was first introduced to the Philippines through the enactment of Act No. 3377, or the "Vocational Act of 1927." [5] On June 3, 1938, the National Assembly of the Philippines passed Commonwealth Act No. 313, which provided for the establishment of regional national vocational trade schools of the Philippine School of Arts and Trades type, as well as regional ...
Ilocos Norte College of Arts and Trades (INCAT) is a public institution in the Philippines founded in 1908. [1] [2] Accredited by the Technical Education and Skills Development Authority, it offers technical and vocational courses [1] [3] [4] as well as teacher education training.

Submerged arc welding (SAW) is a common arc welding process. The first SAW patent was taken out in 1935.
Arc welding power supplies can deliver either direct (DC) or alternating (AC) current to the work, while consumable or non-consumable electrodes are used. The welding area is usually protected by some type of shielding gas (e.g. an inert gas), vapor, or slag. Arc welding processes may be manual, semi-automatic, or fully automated.
This is a list of welding processes, separated into their respective categories. The associated N reference numbers (second column) are specified in ISO 4063 (in the European Union published as EN ISO 4063 ). [ 1 ]
Dry hyperbaric welding involves the weld being performed at raised pressure in a chamber filled with a gas mixture sealed around the structure being welded.. Most arc welding processes such as shielded metal arc welding (SMAW), flux-cored arc welding (FCAW), gas tungsten arc welding (GTAW), gas metal arc welding (GMAW), plasma arc welding (PAW) could be operated at hyperbaric pressures, but ...
On May 10, 2000, the Joint CHED-TESDA Memorandum Circular No. 1, s. 2000, the Implementing Guidelines on the Transfer of CHED-Supervised Institutions (CSIs) to Technical Education and Skills Development Authority (TESDA) was issued. Dr. Geronimo S. dela Cruz, Sr. was the first Vocational School Superintendent of PSAT under TESDA supervision.
