What is shielded metal arc welding course?
Shielded Metal Arc Welding (SMAW) NC II is a short TESDA course in the Philippines that will train you in welding carbon steel plate and pipe components as specified by layout, blueprints, diagrams, work order, welding procedure or oral instructions using shielded metal arc welding equipment.
What is SMAW principle?
Working Principle SMAW It works on the principle of heat produced by the electric arc. The heat produced by a consumable flux coated electrode is used to melts the base metal and fuse them together to form a strong weld joint. It uses a flux coated electrode that melts and acts as filler material.
How much do shielded metal arc welders make?
The salaries of Welder Shielded Metal Arcs in the US range from $45,350 to $64,419 , with a median salary of $50,496 . The middle 57% of Welder Shielded Metal Arcs makes between $50,496 and $54,844, with the top 86% making $64,419.
How hot is shielded metal arc welding?
approximately 11,000 degrees Fahrenheit
Most SMAW arcs have a effective temperature of approximately 11,000 degrees Fahrenheit or 6,100 degrees Celsius.
How long is TESDA welding course?
Shield Metal Arc Welding NC II better known as SMAW is a registered program of LCC from TESDA, it prepares students to acquire competency skills in welding. The program is a 3-Month course, that includes an assessment examination from TESDA, where LCC is known for bagging 100% Rate in SMAW Examination.
What is nc2 in welding?
The Shielded Metal Arc Welding (SMAW) NC II Qualification consists of competencies that a person must achieve to weld carbon steel plate and pipe components as specified by layout, blueprints, diagrams, work order, welding procedure or oral instructions using shielded metal arc welding equipment.
Why is a welding arc shielded?
The primary functions of the shielding gas in the arc welding processes are to provide a suitable medium for the stable operation of a sustained low-voltage arc and to provide shielding from atmospheric contamination.
Which is true about shielded metal arc welding SMAW?
Shielded metal arc welding (SMAW) also known as stick welding, is a manual process using a flux coated consumable electrode with a metal rod at the core. Both protect the weld area from atmospheric contamination. As the metal rod inside the electrode melts it forms a molten pool which becomes the weld.
