A standard scoop of whey protein powder is about 30 grams, which is equivalent to approximately 1/4 cup. That amount of powder has about 110 calories, 2 grams of fat, 1 gram of carbohydrates, no fiber, 1 gram of sugar, 23 grams of protein and 35 milligrams of cholesterol.
For years the industry-standard gas blend for short-circuit welding of stainless steel was a helium-based (85 to 90 percent) trimix with small additions of argon (5 to 10 percent) and CO2 (2 to 5 percent).
Thus the weld metal weight therefore =theoretical weight xQ factor. ( Quantity factor) .This Q factor=2 for TIG welding and 2.5 for SMAW. Hope this thumb rule will help you calculate weight of welding. electrode/wire required for a joint.. Sorry that for your second query for gas consumption I am unable to.
