The benefits of the process include its high deposition rate, efficient use of filler metal, elimination of slag and flux removal, and reduction of smoke and fumes. A disadvantage is that GMAW requires more equipment, making it less portable than shielded metal arc welding (SMAW).
When should I introduce solid food to my baby? As long as your baby shows signs of readiness, your child's doctor may say you can start solids any time around 4 to 6 months. Until then, breast milk or formula provides all the calories and nourishment your baby needs â and can handle.
Try as best you can to offer your baby home-made fare. It's best to use pre-prepared jars or packs of baby food as a stop-gap rather than for all your baby's meals. Even though official guidelines say it's right to start solids at six months, you'll see products on the shelves for babies aged four months (DH 2003).
