1What does MMAW stand for in TESDA welding qualifications?

A.Manual Metal Arc Welding

B.Metal Molding and Welding

C.Mechanized Metal Arc Welding

D.Multi-pass Metal Arc Welding

Explanation: MMAW is Manual Metal Arc Welding. TESDA amended the official title from Shielded Metal Arc Welding (SMAW) to MMAW in 2021 (MEEMAW121), though both terms refer to stick welding with a covered electrode.

2MMAW is also commonly known as:

A.Shielded Metal Arc Welding (SMAW)

B.Gas Metal Arc Welding (GMAW)

C.Gas Tungsten Arc Welding (GTAW)

D.Flux-Cored Arc Welding (FCAW)

Explanation: MMAW and SMAW are the same stick welding process. The electrode coating provides shielding gas and slag; GMAW, GTAW, and FCAW are different arc processes.

3In the AWS electrode classification E6013, what does the "60" indicate?

A.Minimum tensile strength of 60,000 psi (60 ksi)

B.Electrode diameter of 0.060 inch

C.Maximum amperage of 60 amps

D.Carbon content of 0.60 percent

Explanation: The first two digits after "E" indicate minimum tensile strength in thousands of psi. E6013 is a 60 ksi electrode suitable for mild/carbon steel.

4In AWS classification, the third digit "1" in E7018 means the electrode can be used:

A.In all positions (flat, horizontal, vertical, and overhead)

B.Only in flat position

C.Only with AC current

D.Only for stainless steel

Explanation: A third digit of 1 designates all-position capability. E7018 is widely used for structural carbon steel plate in multiple positions.

5What does the "18" in E7018 primarily indicate?

A.Low-hydrogen iron-powder coating; typically DC electrode positive

B.Cellulose coating for deep penetration root passes

C.Rutile coating for thin sheet only

D.Nickel alloy for cast iron repair

Explanation: The fourth digit 8 identifies a low-hydrogen, iron-powder coating. E7018 produces strong, ductile welds and is standard for structural plate work.

6Which electrode is commonly selected for general-purpose all-position work on thin carbon steel plate with smooth arc and easy slag removal?

A.E6013

B.E7024

C.E6010

D.E7028

Explanation: E6013 is a rutile-coated, all-position electrode valued for smooth arc, moderate penetration, and easy slag removal on thin plate and general repair.

7For structural carbon steel plate requiring low-hydrogen deposits and high strength, which electrode is most appropriate?

A.E7018

B.E6013

C.E6012

D.E7024

Explanation: E7018 is a low-hydrogen electrode with 70 ksi minimum tensile strength, preferred for structural plate and multi-pass groove work.

8Standard E7018 electrodes are typically run on:

A.DC electrode positive (DCEP / reverse polarity)

B.DC electrode negative only

C.AC only without rectification

D.No electrical connection—chemical reaction only

Explanation: E7018 is normally used with DCEP (reverse polarity) for stable arc and proper penetration on carbon steel.

9Which electrode can commonly operate on both AC and DC?

A.E6011

B.E7018 (standard low-hydrogen)

C.E6010 (cellulose DC only)

D.E7024 (flat position only)

Explanation: E6011 has a potassium coating allowing AC or DC use, useful when only AC machines are available.

10When setting up an MMAW machine for carbon steel plate, work lead (ground) is attached to:

A.The workpiece or welding table to complete the electrical circuit

B.The electrode holder only

C.The welding helmet

D.The slag chipping hammer

Explanation: The work clamp completes the circuit between the power source and base metal. Current flows through the arc from electrode to workpiece.
