NOTE:<br />
(1) Specifications are not exact duplicates. Information is supplied only for general comparison.<br />
Testing in accordance with any other Schedule in that<br />
Table shall be specifically required by the purchase<br />
order. In such cases, acceptance of the material shipped<br />
shall be in accordance with those requirements.<br />
A4. Certification<br />
The act of placing the AWS specification and classification<br />
designations on the packaging enclosing the<br />
product or the classification on the product itself, constitutes<br />
the supplier’s (manufacturer’s) certification that<br />
the product meets all of the requirements of the specification.<br />
The only testing requirement implicit in this certification<br />
is that the manufacturer has actually conducted<br />
the test required by the specification on material that<br />
is representative of that being shipped and that the<br />
material met the requirements of the specification. Representative<br />
material, in this case, is any production<br />
run of that classification using the same formulation.<br />
“Certification” is not to be construed to mean that tests<br />
of any kind were necessarily conducted on samples of<br />
the specific material shipped. Tests on such material<br />
may or may not have been conducted. The basis for<br />
the certification required by the specification is the<br />
classification test of “representative material” cited<br />
above, and the “Manufacturer’s Quality Assurance Program”<br />
in ANSI/AWS A5.01.<br />

A5. Ventilation During Welding<br />
A5.1 Five major factors govern the quantity of fumes<br />
to which welders and welding operators are exposed<br />
during welding:<br />
(a) Dimensions of the space in which welding is<br />
done (with special regard to the height of the ceiling);<br />
(b) Number of welders and welding operators working<br />
in that space;<br />
(c) Rate of evolution of fumes, gases, or dust, according<br />
to the materials and processes used;<br />
(d) The proximity of the welders or welding operators<br />
to the fumes as the fumes issue from the welding zone,<br />
and to the gases and dusts in the space in which they<br />
are working;<br />
(e) The ventilation provided to the space in which<br />
the welding is done.<br />
A5.2 American National Standard Z49.1, Safety in<br />
Welding and Cutting (published by the American Welding<br />
Society), discusses the ventilation that is required<br />
during welding and should be referred to for details.<br />
Attention is drawn particularly to the section of that<br />
document, entitled “Health Protection and Ventilation.”<br />
A6. Welding Considerations<br />
A6.1 Titanium and titanium alloys can be welded<br />
by gas tungsten arc, gas metal arc, plasma arc and
