Require a Recessed Countersunk Hole?

The Hole Tool in Inventor 2018 has received a new option, that new option is the “Extend Start” tool.

Neil Markham writes, if you have created holes that are not perpendicular to the start plane, you will have noticed a fragment of material left behind in the hole.

The sale and manufacture of wash-off products containing plastic microbeads will be banned in New Zealand earlier than previously expected, Associate Environment Minister Scott Simpson announced today.

“Microbeads pose a high risk to our aquatic and marine environments. They are too small to retrieve or recycle, do not biodegrade, and are mistaken by marine life for food, causing long-term damage to marine animals,” Mr Simpson says.

The ban will take effect six months after World Trade Organisation notification, which will take place when the regulations are gazetted in November. Microbeads will be fully banned in New Zealand by May 2018.

“We consulted in January 2017 on a proposal to ban microbeads in personal care products like facial cleansers and toothpastes. We received over 16,000 submissions that all supported a ban. Many submitters urged the Government to broaden the scope of the proposed ban to include other products containing microbeads.

“In response, we have widened the scope of the ban to include all ‘wash-off’ products for visual appearance, exfoliating, cleansing or abrasive cleaning purposes that contain plastic microbeads. As well as personal care products, this includes household, car or other cleaning products.

“Foodstuffs have already removed products with plastic microbeads from their shelves. Major manufacturers are also phasing out plastic microbead ingredients.

“This ban is part of a global initiative to reduce the amount of plastic ending up in oceans. The New Zealand ban parallels similar initiatives in the United States, United Kingdom, Canada, the European Union and Australia to ban or phase out plastic microbeads in products.

“New Zealand is a small consumer of plastic microbead products by international comparison but this initiative is important for maintaining New Zealand’s good name in marine stewardship. We have responsibility for one of the largest areas of ocean, we have one of the best fishery management systems, we are leading with conservation measures like the Ross Sea Marine Protected Area and this initiative on microbeads will enhance our clean, green reputation.”

Following specified pipe welding procedures and ensuring proper weld preparation can save significant time and money and ultimately improve productivity of the entire operation.

No matter the welding process being used, proper preparation before you get started is key to ensuring quality in the finished weld. Taking the necessary steps to prepare the weld also can reduce the risk of weld failure as well as wasting time and money on rework and consumables.

Proper weld preparation in pipe welding helps prevent problems such as weld inclusions, slag entrapments, hydrogen cracking, lack of fusion, and lack of penetration. Consider the following key points for cleaning and preparing the weld joint and avoiding some common mistakes to achieve success in pipe welding.

Cleaning and Prep

Joint preparation and cleaning go hand-in-hand. Which happens first depends on the state in which the pipe is received. Some welding operators, especially on outdoor job sites, may be responsible for cutting the pipe and beveling edges. But in some applications, often performed in pipe shops, the cutting and beveling are handled by someone else before the welder receives the pipe.

Proper joint preparation—and whether it’s beveled, grooved, or notched—is often dictated by the qualified weld procedure, which should ensure access to the joint and proper penetration and weld strength for the application. Once the pipe is cut using an oxyfuel torch, plasma cutter, cutting machine, or other tool, and the bevel is established with a grinder or by machining, be sure to clean the inside and outside of the pipe joint and the bevel.

If the pipe was cut with a machine, it’s likely a lubricant was used, so be sure to remove it during cleaning to reduce the risk of hydrogen inclusions. Cutting with an oxyfuel torch or plasma cutter typically leaves a slag or oxide layer on the cut edge. Be sure to clean this to prevent inclusions and porosity.

Remove any paint, oils, and dirt on the base material before welding; otherwise, these materials could make their way into the weld and cause inclusions or porosity that could harm weld integrity and cause it to fail. Clean the area 1 to 2 inches from the weld joint and the tie-in points, where the lacquer coating on the pipe’s outside surface meets the bevel.

While some welding processes or filler metals are more forgiving to dirt or mill scale on the material, don’t rely on the belief that dirt and oil can be burned off during welding. Any foreign material in the weld can cause problems later.

Part Fit-up and Tacking

Proper part fit-up ensures that the joint is set uniformly from start to end, resulting in weld consistency throughout the part. It helps prevent problems with lack of penetration or too much penetration, issues that can decrease the service life of the finished weld.
