     More than 10 years ago, it was difficult to buy a tasty pineapple. The fruits that made it to the UK were

green on the outside and, more often than not, hard with an unpleasant taste within. Then in 1996, the Del

Monte Gold pineapple produced in Hawaii first hit our shelves.

     The new type of pineapple looked more yellowy-gold than green. It was slightly softer on the Outside

and had a lot of juice inside. But the most important thing about this new type of pineapple was that it was

twice as sweet as the hit-and-miss pineapples we had known. In no time, the Del Monte Gold took the

market by storm, rapidly becoming the world's best-selling pineapple variety, and delivering natural levels

of sweetness in the mouth, up until then only found in tinned pineapple.

     In nutrition (营养) it was all good news too. This nice-tasting pineapple contained four times more vitamin

C (维生素C) than the old green variety. Nutritionists said that it was not only full of vitamins, but also good

against some diseases. People were understandably eager to be able to buy this wonderful fruit. The new type

of pineapple was selling fast, and the Del Monte Gold pineapple rapidly became a fixture in the shopping basket

of the healthy eater.

     Seeing the growing market for its winning pineapple, Del Monte tried to keep the market to itself. But other

fruit companies developed similar pineapples, Del Monte turned to law for help, but failed.Those companies

argued successfully that Del Monte's attempts to keep the golden pineapple for itself were just a way to knock

them out of the market.

某化工企业拟建化工机电工程项目，面向社会公开招标。要求投标人具有一级承包资质。有A、B、C、D四家承包单位通过了资格预审。E单位为化工机电二级资质，F单位为土建安装一级资质，两家单位组成联合体进行投标。最终该项目由A公司中标，并签订施工合同，合同约定所有设备由化工企业提供，对应施工材料由A公司自行采购，但必须符合施工要求和质量标准。项目开工后，经过化工企业同意，A公司将部分管道焊接工作分包给具有相应资质的G分包单位。施工过程中，对G分包单位的焊接质量进行检查，发现多处质量不合格，经排查，发现G分包单位擅自更改了焊接方法。A公司首次租赁的吊车进场验收不合格，被化工企业拒绝施工，于是第二次租赁了证件齐全的吊车，耽误了工期10天，A公司向化工企业递交了索赔意向书。项目验收完毕后，A公司参加了化工企业组织的联动试运行和负荷试运行。

擅自改变焊接方法是否需要重新进行工艺评定？如何评定？
